HYDROGARBON-MIX'IJURE HEATER.

Specification of Letters Patent.

\ Patented July 2, 1918.

Application filed April 7, 1917. Serial No. 160,514.

To GZZ' whom it may concern 'Be it known that I, WILLIAM A. PERKINS, acitizen of the United States, residing at Cortland, in the county ofCortland and State of New York, have invented new and usefulImprovements in Hydrocarbon-Mixture Heaters, of which the following is aspecification.

This invention relates to a heater especially adapted to be used forheating a hydrocarbon mixture as it passes through a manifold and beforeit is introduced into the engine cylinder and it consists in the novelfeatures hereinafter described and claimed.

An object of the invention is to provide a heater of simple and durablestructure adapted to be applied to the manifold of an internalcombustion engine at a point between the intake point of the cylinderand the carbureter, and which. is supplied by a heating medium conductedfrom the exhaust of the engine whereby the mixture is subjected to theheat prior to its introduction into the engine cylinder and thus is putin proper condition for explosion.

With this object in view the'device includes an enlarged portion in themanifold pipe at a point between the carburetor and the intake port ofthe engine cylinder and a casing inserted in the said enlargement.Suitable pipes connect the said casing with the exhaust pipe of theengine and short sections of pipe pass through the said casing and theinner portion of the casing is spaccd' from the outer wall of theenlargement, thus providing ample room to permit the mixture to passthrough the manifold.

. In the accompanying drawing Figure 1 is a side view of an engineshowing the heater applied. Fig. 2 is a vertical sectional view of theheater. Fig. 3 is a transverse sectional view of the same. Fig. 4: is aperspective view of the casing used in the heater.

As illustrated in the accompanying drawing. the engine. 1 is of a'usualtype and is provided with a manifold 2 which in turn is connected with acarbureter 3 in a usual manner. The heater comprises an enlargement 4;provided on the manifold 2- at a point between the ends thereof. Acasing 5 is inserted in the enlargement 4 from one side thereof and theinner surface of the said casing 5 is spaced from the outer surface ofthe enlar ement 4.. A suitable packing 6 is interpose between the outerwall of the casing 5 and the enlargement 4 and serves as means forclosing the joint between the casing and the enlargement. Pipes 7 pass10ngitudinally through the casing 5 and are spaced from each other. Anysuitable number of pipes 7 may be employed. A pipe 8 is connected withthe upper portion of the easing 5 and is also connected with the exhaustpipe 9 of the engine preferably at a-point where the said pipe 9 isheated the mostjn consequence of the exhaust gases passing through thesame; A valve controlled funml 10 may be applied to the pipe 8 in thevicinity of the casing 5. A pipe 11 is conneeted with the lower portionof the casing 5 and may conduct the exhaust gases from the same.

In operation, the mixture is drawn through the manifold 2 and theenlargement 4 by the action of the engine piston in a usual manner. Atthe same time the exhaust gases are expelled from the engine cylinderand some of the said gas passes through the p pe 8 into the casing 5 andheats the same and the pipes 7 Therefore as the mixture passes along thesides of the casin 5 and through the pipes 7 it is subjecte to the heatand thus the mixture is heated prior,

to its introduction into the engine cylinder. As hereinbefore stated thegas. which enters the casing 5 may eseape from the same through the pipe11; When it is desired to,

clean the heater of the accumulation of carbon or other foreign mattergasolene 1s poured into the funnel 10 and the valve thereof is openedwhereby the said gasolene may gravitate into the casing 5 and .cut thesaid foreign material. loose which may pass out with the gasolenethrough the pipe 11. In a similar manner hot water may be introducedinto the casing 5 to aid in starting the engine when the same is cold.

From the foregoing description taken in conjunction with theaccompanying drawing, it will be. seen that a hydrocarbon heater ofsimple and durable structure is provided and that the same may beconveniently used for efficiently heatin ahydrocarbon mixture priortoits intror uction 106 into the cylinder of a hydrocarbon engine.

Having described the invention what is claimed is In combination with amanifold pipe hav ing a diametrically enlarged portion, a 5 heatercomprising a casing inserted through the side of the enlargement, thesurface of the casing being spaced from the inner surface of theenlargement and approximately parallel with the same, spaced pipespassin through the casing and means connected 10 with the side of thecasing for introducin a heating, agent into the casing and aroun thepipes.

In testimony whereof I afiix my signature.

WILLIAM A. PERKINS.
